Yamaha 250 Sho Prop help at Elevation
Hoping someone can steer me in the right direction on what prop to purchase for optimum speed & performance at this lake. This run was empty and I didnt even think to fill up livewells and see what happened. I do have to chop the throttle a couple two-three times on holeshot to boost rpm’s as soon as it hits 3000 and above it takes off. Looking for suggestions for tournament load with partner and livewells loaded.
Boat: 2015 Phoenix 721
10” Atlas Hyd JP
Dual 10ft 3 stage Talons
4 batteries
1/2 tank of gas. Approx 20 Gallons.
Motor: 2015 Yamaha Vmax SHO 250
Prop: Yamaha Vmax SHO T2 25P
Light load 2 guys 200lbs tackle and live wells empty. Hydraulic jackplate set at 20 (1.5”) p2p at take off and lowered to 14 (3”) for run.
Elevation: Lake Powell Utah/AZ 3500ft.
Boat performance: Air Temp 68*, Water Temp 60*, RPM 5414, GPS Speed 68.2 mph
Was told I should go with a 22pitch Yamaha T2 prop. Seems like rpms would be right and holeshot would definitely be improved but I am worried about losing my top end. Anyone have an approximate difference in top end between a 22p & 23p.

Try the 22T2... You may gain speed as the motor makes more HP at 6000 rpms. A 22P Bravo1 FS or Marks Razor4 XL may also be another good option.

Can anyone give pros and cons or advantages of one over the other between the 22 T2, bravo1 fs & razor4 xl.
Obviously the bravo and razor 4 are four blades and would probably add stability but may sacrifice top end?

These 4 blades will give the best holeshot, acceleration, handling, load carrying, stay on plane at slower speeds etc.... At the expense of 1-3 mph top end of your fastest prop that will fall short on all other things mentioned.
